How to choose the right yellow sand dryer? What are the safety precautions for its operation?
The following are the methods of selecting the right yellow sand dryer and the safety points of its operation:
How to choose the right yellow sand dryer
Output demand
According to their own production scale and output requirements to choose yellow sand dryer. For example, if a large sand farm needs to dry a large amount of yellow sand every day, it needs to choose a dryer with large processing capacity and large cylinder diameter and length to meet the production demand; while a small construction site or processing plant with smaller production demand can choose a small dryer with relatively low processing capacity.
Drying effect
Different drying process and equipment structure will affect the drying effect. For example, rotary dryer drying uniformity is better, which can effectively guarantee the drying quality of yellow sand; while mesh belt dryer is suitable for occasions with higher requirements on the particle size and shape of yellow sand after drying. In addition, we also need to pay attention to the thermal efficiency of the dryer, high thermal efficiency equipment can reduce energy consumption at the same time, improve the drying speed and effect.
Energy type
Consider the local energy supply and cost to choose the type of energy. If the supply of natural gas is sufficient and the price is reasonable, you can choose gas-type yellow sand dryer, which has the advantages of cleanliness and high combustion efficiency; if there are abundant electric power resources, the electric heating dryer has the characteristics of simple operation and precise temperature control; for some areas with a large amount of biomass resources, biomass pellet fuel dryer can reduce costs and also realize the recycling of resources.
Equipment quality
Choose a well-known brand and reputable equipment manufacturer, whose product quality and after-sales service are more guaranteed. To check the material of the equipment, such as whether the cylinder is made of good wear-resistant steel plate, whether the manufacturing process of the key components is exquisite, you can also refer to the use evaluation and cases of other users to understand the stability and stability of the equipment.
Price and budget
Under the premise of meeting the production needs and quality requirements, choose the right yellow sand dryer according to your budget. Don't blindly pursue high-price equipment, nor can you choose low-quality products in order to save costs. It is necessary to comprehensively consider the cost-effectiveness of the equipment, including the price of the equipment, operating costs, maintenance costs and other factors.
Yellow sand dryer operation safety attention points
Before starting the equipment
It is necessary to comprehensively check the various parts of the equipment, including the transmission device, heating system, feeding device, etc., to ensure that the connection is firm and there is no looseness or damage. At the same time, it is necessary to clean up the debris around the equipment and guarantee a spacious operating space to avoid collision and other safety accidents during the operation of the equipment.
Feeding process
Strictly control the feeding amount and feeding speed, to avoid feeding too fast or too much to cause equipment blockage. If the screw feeder is used, ensure its normal operation to prevent the screw blade from jamming or being damaged. At the same time, pay attention to observe the humidity and particle size of the yellow sand to avoid excessive humidity or uneven particle size affecting the drying effect and equipment operation.
During the operation of the equipment
The operator shall not leave the post without authorization, and shall pay close attention to the running status of the equipment, including temperature, pressure, speed and other parameters. If the temperature is found to be abnormally high or low, it may be the fault of the heating system, and it should be shut down immediately for checking; if the equipment vibrates too much or has abnormal noise, it may be the looseness or wear of the parts, and it should be investigated and dealt with in time.
When maintenance and overhaul
Before carrying out maintenance and overhaul of the dryer, the power supply must be cut off and the warning sign of “no closing gate” must be hung up. When entering the inside of the cylinder for overhauling, make sure the ventilation is good to prevent the accumulation of carbon monoxide and other harmful gases, and at the same time, take safety measures, fasten the safety belt, and have a person to supervise from the outside.
Fire safety
As the drying process involves high temperature, special attention should be paid to fire safety. It is strictly prohibited to pile up flammable and explosive articles around the equipment, and sufficient quantity of fire extinguishing equipment should be equipped. Regularly check the electrical lines of the equipment to prevent fires caused by aging lines and short circuits.
